1. You want to make sure the CableCARD you are putting in your Roamio has this part number: 514517-017-00. (On the back, above the barcode.) If your Roamio has a CableCARD with a different part number, you'll need to call Verizon and have them swap the card.

2. If you have the correct part number, but your HBO or other premium channels are still "pixelating" then it is likely that your CableCARD is "authorized" but not "paired". Call Verizon's activation line 1-888-897-7499 and keep asking for "tech support". Once you have reached someone in tech support, tell them your CableCARD is authorized but not paired, and ask them to "Manually Validate Set Top Box". (I have been told this instruction is what has worked for other customers.)

I will let you know if we are able to release an update that allows the older cards to work. For now, please make sure you have the newest card.

I'm having the same issue. Terrible pixelation on HBO and Cinemax.
I hooked the roamio up yesterday, gave up after 3 calls to Verizon to pair the card (moved it from Windows Media Center)
Called again today, and he was about to give up but tried one more thing. Whatever it was - it worked. I can now tune both channels but the pixelation makes them unwatchable.
I have several attenuators left by the original installer and tried multiple configurations. I think it may have worked at one point but I can't recreate it. When I do hook them up I completely loose some other channels.

I'm not sure what to do. I'm assuming if it wasn't paired/activated correctly, then I wouldn't get the premium channels at all. Is it possible a new card would fix it? It worked fine in the media center.

I don't have Fios, but may be moving to a Fios area so have been reading up on it. I read somewhere that you should suggest to your Verizon tech to use a system called DTI Express for authorizing your CableCard. Apparently they won’t try it unless you ask.

Just joining the party with this issue. TiVo tech support is suggesting attenuators which I have not found to try yet. I did try three separate cable cards -- all of which worked fine in my premier on the same exact cable line.

TiVo tech support fixated on the 100 signal strength, i also have 42 SNR

Picture quality is terrible, massive horizontal disruption. It seems to clear for about 2-3 seconds, then goes back to garbled for 10-12 seconds.

I'm not use Moca although I have the Verizon router with Moca enabled. I did add a filter for Moca on the Roamio and it had no impact on my problem. I had a Ceton card for a while and Moca could interfere with a number of channels depending on the frequency you have your Moca set to. The filter solved that problem. I'm using the ethernet hookup.

I have a Roamio Pro.

The copy once channels are HBO, Cinemax, and Ch 131. I don't remember seeing any others.

Email her your TSNs, I would include any TSNs you have tried on and whether you currently see this.

Also describe exactly what you are seeing in your situation and what you have attempted to resolve so they can start researching. The more information the better. I would also include your setup and details similar to what I mentioned above. Is MoCa enabled on the TiVo, is it off? Is MoCa on the router on or off? Does your Premiere on the same cable work? etc. Anything you can think of no matter how insignificant might help.
